Secure file sharing system and method

A file sharing system comprising:

• an electronic management device equipped with symmetric encryption software and management software;
• a sender electronic device associated with a first user and having access to an original file;
• a recipient electronic device associated with a second user;
• wherein the electronic management device, the sender electronic device and the recipient electronic device are connectable to a telecommunication network for an exchange of data/information;
• wherein the system, said symmetric encryption software, and the management software are configured to:
• encrypt the original file to obtain an encrypted file-using a private key that is unknown to the recipient electronic device;
• insert inside a host file the encrypted file and a link to the electronic management device obtaining an enriched host file having one of the following types:
• docx, pptx, xlsx, pdf;
• access the enriched host file through the recipient electronic device and communicate with the management electronic device through the link by activating an authorization procedure;
• carry out the authorization procedure by means of a data/information exchange between the electronic management device, the sender electronic device and the recipient electronic device to provide an authorization to the second user;
• and
• decrypt the encrypted file by the electronic management device to define a decrypted file, and make the decrypted file at least viewable at the recipient electronic device when the authorization is granted to the second user.
